Should I start exercising now?

SATURDAY, APRIL 25, 2020 [EXTENDED LOCKDOWN IS REAL]
Maybe I’m just getting anxious but I felt like I’m in prison. I haven’t been outside for five days now and I am located in the 3rd floor of our apartment building. Having said that, I have not seen any sunshine for five days. On top of that, I’m awake at night while asleep for most of the morning time.
